Description

Technical Field

[0001] The present invention relates to the technical field of construction and installation of power generation equipment, and particularly to a modular installation system for a concrete tower barrel of a wind turbine generator. Background Art

[0002] At present, the construction of large wind turbine generators has become a new energy development trend. In particular, the construction of onshore large wind turbine generators is beneficial to increasing the proportion of renewable energy, optimizing the local power supply system structure, reducing the local power supply pressure, etc. In recent years, the application of steel-concrete hybrid wind turbine generator tower barrels has been relatively widespread. It has the advantages of convenient production, fast construction, stable structure, and low construction cost. Most importantly, this structure can raise the hub height of the wind turbine to 120m or more, enabling better utilization of wind resources. The precast prestressed segmented concrete tower barrel installation construction method is widely adopted, which has the advantages of short construction period, controllable quality, and low cost.

[0003] During the installation and construction of the current segmented concrete tower barrel, multiple precast concrete module plates are first spliced into a section of the barrel body, and then a lifting device is used to connect with multiple concrete module plates of this section of the barrel body for lifting and hoisting it above the constructed barrel body to achieve the function of splicing each segment one by one. Multiple concrete modules of a section of the barrel body can be pre-connected by bolts. During the lifting process, lifting rings or lifting nails and other structures are installed on the top of each concrete module, and steel cables are used to lift it. However, the force on each concrete module plate is dispersed. When this section of the barrel body tilts during the lifting process, one of the concrete module plates will bear a large tensile force, which may cause the connection bolts and other structures to be distorted and deformed, affecting the safety of the barrel body hoisting.

[0004] Therefore, there is an urgent need for a modular installation system for a concrete tower barrel of a wind turbine generator to solve the problem that when this section of the barrel body tilts during the lifting process, one of the concrete module plates will bear a large tensile force, thus affecting the hoisting safety.

Detailed implementation manners

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] As shown in the Figure 1 and Figure 2 accompanying drawings, a modular installation system for a concrete tower barrel of a wind turbine generator set according to an embodiment of the present invention includes a lifting ring 1, a support disk 17, several adjusting components, and a steel cable 6. The adjusting components include a drive box 7, a hydraulic cylinder 8, and a limiting component. A lifting ring 1 is provided at the center of the upper end of the support disk 17, and several drive boxes 7 are arranged in an equidistant array around the support disk 17. A hydraulic cylinder 8 is installed inside the drive box 7. A support rod 10 is provided at one end of the telescopic rod 9, which is the output end of the hydraulic cylinder 8, and away from the hydraulic cylinder 8. A steel cable 6 is connected to the support rod 10. An opening for the steel cable 6 to extend out is provided at the lower end of the drive box 7. The steel cable 6 extending out from the opening is used to connect to the upper end of the modular plate 2. The hydraulic cylinder 8 is used to drive the telescopic rod 9 to carry the support rod 10 and one end of the steel cable 6 to move closer to or away from the support disk 17. The limiting component is arranged inside the drive box 7 and is used to limit or cancel the movement of the support rod 10.

[0032] Through the settings of the lifting ring 1, the support disk 17, the adjusting components, etc. of the present invention, during the lifting process of a section of the barrel spliced by a plurality of precast concrete modular plates 2, the tension of the steel cable 6 can be conducted by the support rod 10. When the barrel is tilted, resulting in an increase or decrease in the tension received by the support rod 10 in some of the adjusting components, the hydraulic cylinder 8 can be used to drive the support rod 10 to move, so as to adjust the tightness or use angle of the steel cable 6, thereby adjusting the tension of the steel cable 6, so that the tilted barrel can be restored to balance, ensuring that the barrel always maintains a balanced state during the lifting process, reducing the influence of extrusion on the modular plate 2, etc., and solving the problem of lifting safety caused by tilting. Among them, the limiting component can increase the means of restricting the movement of the support rod 10 when the support rod 10 is not adjusted, further ensuring the stability during lifting; at the same time, the central symmetric distribution structure among the lifting ring 1, the support disk 17, and several adjusting components increases the stability of the structure during use, and the external lifting equipment can be connected by using the lifting ring 1.

[0033] In this solution, a chute 30 for the sliding connection of both sides of the support rod 10 may be provided inside the above-mentioned drive box 7, so as to guide and support the movement of the support rod 10.

[0034] As shown in the attached Figure 3 figure, in another specific embodiment based on the above, the limiting component includes a stabilizing rod 27, a moving sleeve 11, a limiting shaft 12 and a limiting adjustment component. The limiting adjustment component includes a moving shell 13, a limiting block 14 and an adjustment driving component. A stabilizing rod 27 consistent with the moving direction of the telescopic rod 9 is provided inside the drive box 7. A moving sleeve 11 is slidably arranged on the stabilizing rod 27. A limiting shaft 12 is provided on the moving sleeve 11. The support rod 10 is connected to the moving sleeve 11. A moving shell 13 is provided on one side of the limiting shaft 12. Several limiting blocks 14 are spaced apart on the side of the moving shell 13 close to the limiting shaft 12. The adjustment driving component is arranged inside the moving shell 13 and is used to connect and drive the moving shell 13 to move close to the limiting shaft 12 and limit the limiting shaft 12 between two limiting blocks 14, or to move away from the limiting shaft 12 and release the limiting shaft 12 from the restriction of the limiting blocks 14.

[0035] In this way, the movement of the support rod 10 can be restricted and guided by the stabilizing rod 27 and the moving sleeve 11, and the adjustment driving component is used to connect and drive the moving shell 13 to move close to the limiting shaft 12 on the moving sleeve 11 and limit the limiting shaft 12 between two limiting blocks 14 to ensure the stability of the support rod 10 when it does not move, or the adjustment driving component drives the moving shell 13 to move away from the limiting shaft 12 and release the limiting shaft 12 from the restriction of the limiting blocks 14 to realize the movement adjustment of the support rod 10.

[0036] As shown in the attached Figure 4 and the attached Figure 5 figure, wherein, in a further embodiment based on the above, the adjustment driving component includes a sliding rod 21, a sliding block 22, an electromagnet 20, a tension spring 24 and an inclined rod 23. The electromagnet 20 is installed inside the moving shell 13 through the symmetrically arranged sliding rods 21 on both sides. A sliding block 22 is slidably arranged on each of the two sliding rods 21 on both sides. One end of an inclined rod 23 is hinged to one side of the sliding block 22. A transverse groove 26 is formed on the side wall of the moving shell 13. The two inclined rods 23 can move out from the transverse groove 26 and are hinged to the inner wall of the drive box 7. The transverse groove 26 can ensure the movement of the inclined rod 23. A tension spring 24 is connected between the side of the sliding block 22 away from the electromagnet 20 and the inner wall of the moving shell 13. The tension spring 24 is sleeved on the sliding rod 21 and is used to drive the sliding block 22 to move away from the electromagnet 20. The electromagnet 20 is used to be energized and adsorb the two sliding blocks 22 to move closer to each other and drive the moving shell 13 away from the limiting shaft 12.

[0037] In this solution, the slider 22 is made of metal. In this way, when the electromagnet 20 is energized, it can generate magnetic force to adsorb the slider 22, drive the moving shell 13 away from the limit shaft 12, and thus release the restraint on the support rod 10.

[0038] Among them, in the above further embodiment, a cross bar 25 is installed on both sides of the moving shell 13 and located on both sides of the adjustment driving component. One end of the cross bar 25 away from the moving shell 13 is fixedly installed on the inner wall of the driving box 7, and the other end is slidably inserted into the moving shell 13, and the sliding direction of the moving shell 13 on the cross bar 25 is the same as the direction in which the adjustment driving component drives the moving shell 13 to move. In this way, the movement of the moving shell 13 can be limited by the cross bar 25.

[0039] Among them, a spring 28 for resetting is provided between the moving shell 13 and the inner wall of the driving box 7 on the cross bar 25.

[0040] Among them, a partition 29 is respectively provided on both sides of the adjustment driving component inside the moving shell 13. The sliding rod 21 and other structures of the adjustment driving component are arranged between the two partitions 29. The two sides of the moving shell 13 away from each other are respectively set as sliding cavities, and the cross bar 25 is slidably arranged in the sliding cavity. In this solution, a stop block for preventing slipping can be provided at the end of the cross bar 25 located in the sliding cavity.

[0041] Among them, in the above further embodiment, the limit block 14 has a right triangle structure. The limit block 14 is fixedly installed on the moving shell 13 through a right angle side, and the hypotenuse is arranged along the moving direction of the support rod 10 towards the support disk 17. In this way, it is convenient for the hydraulic cylinder 8 to drive and tighten the steel cable 6.

[0042] As shown in the Figure 6 attachment, in another specific embodiment based on the above, a pressure sensor 16 is further included. A connecting shell 15 is installed on the support rod 10. The telescopic rod 9 slides through the connecting shell 15, and one end passing through the connecting shell 15 is fixedly connected with a disk 18. Several pressure sensors 16 are installed around the telescopic rod 9 at one end of the disk 18 close to the telescopic rod 9. The pressure sensors 16 are used to contact the connecting shell 15 and are electrically connected to the hydraulic cylinder 8. In this way, the change of pressure can be sensed by the pressure sensor 16, and the start and stop of the hydraulic cylinder 8 can be driven according to different situations. At the same time, the pressure sensor 16 is fixed between the connecting shell 15 and the disk 18, and the data of the traction tension conducted by multiple groups of support rods 10 can be detected and collected, which is convenient for balancing the tension of multiple groups of steel cables 6.

[0043] As shown in the Figure 7As shown in the figure, in another specific embodiment based on the above, it further includes a bearing assembly. The bearing assembly includes a lifting pin 4 and a duckbill buckle 5. The lifting pin 4 is installed on the top of the module plate 2. One end of the duckbill buckle 5 is connected to the steel cable 6, and the other end of the duckbill buckle 5 is used to be sleeved on the lifting pin 4. In this way, the module plate 2 is connected through the bearing assembly and the steel cable 6. In this solution, at least two lifting pins 4 are installed on the top of each module plate 2. Each lifting pin 4 is correspondingly connected to a steel cable 6. The steel cables 6 connected to each module plate 2 form a group, and each group of steel cables 6 is jointly connected by the corresponding support rod 10.

[0044] Among them, the above-mentioned duckbill buckle 5 is connected to the steel cable 6 through a bow shackle 19. Among them, the bow shackle 19 is connected between the steel cable 6 and the duckbill buckle 5, which can facilitate the removal of the steel cable 6 after the cylinder assembly is completed.

[0045] A specific implementation manner of the present invention is as follows:

[0046] A cylinder spliced by eight concrete precast module plates 2 is installed on the mounting seat 3 as a base. Adjacent two module plates 2 in each section of the cylinder can be spliced and fixed by bolt connection. In the cylinder to be hoisted, lifting pins 4 are installed on the top of the module plates 2, and there are two lifting pins 4 on the top of each module plate 2 to play the role of evenly bearing the weight. The staff connects the steel cable 6 to the lifting pin 4 through the bow shackle 19 and the duckbill buckle 5, and connects to the external lifting equipment through the lifting ring 1 to lift the spliced module plates 2 and perform piecemeal splicing one by one. At the same time, each module plate 2 is connected to two lifting pins 4 through two steel cables 6 respectively, which can effectively improve the stability during lifting.

[0047] While the steel cable 6 hoists the module plate 2, it will transmit the inclined traction force to the support rod 10. The support rod 10 cooperates with the connection shell 15 and the disc 18 to conduct the pressure sensor 16. The pressure sensor 16 detects the inclined traction force of the current steel cable 6. By analyzing the values transmitted back by multiple groups of pressure sensors 16, the hydraulic cylinder 8 at the current position can be automatically adjusted through an external controller or a set value;

[0048] When the pressure sensor 16 detects that the pulling force value of the current steel cable 6 is less than the set value, the hydraulic cylinder 8 can be started to drive the support rod 10 to move and tighten the steel cable 6. Specifically, when the support rod 10 moves, it drives the moving sleeve 11 and the limit shaft 12 to move. When the limit shaft 12 moves, it pushes the inclined surface of the limit block 14. The limit block 14 cooperates with the moving shell 13 and the inclined rod 23 to stretch the tension spring 24. When the limit shaft 12 finishes moving and the cylinder returns to the balanced state, the tension spring 24 has the function of stretching and storing energy, which can reset the slider 22, thereby resetting the moving shell 13. The limit shaft 12 is prevented from moving or resetting again through the limit block 14, realizing the function of fixing the steel cable 6.

[0049] When the pressure sensor 16 detects that the tensile force value of the current steel cable 6 is greater than the set value, the electromagnet 20 is activated to adsorb the slider 22. At this time, the slider 22 will move to contact the electromagnet 20, driving the moving shell 13 away from the limiting shaft 12 to release the limit on the support rod 10, so that the hydraulic cylinder 8 can drive the support rod 10 to move and release the steel cable 6. When the limiting shaft 12 has moved and the cylinder body returns to the balanced state, the electromagnet 20 releases the adsorption on the slider 22, and the moving shell 13 resets under the action of the tension spring 24 or the spring 28 until the limiting block 14 limits the limiting shaft 12, so that the cylinder body always maintains a balanced state during the hoisting process, reducing the extrusion effect on the module plate 2.
